Understanding the relevant aspects of the construction of knowledge in science, as well as the elements that are an essential part of a scientific inquiry, need to be discussed in teacher training courses in the area of natural sciences. This study aimed to identify and classify investigative elements present in the conceptions of undergraduates…

Emory University has had a long relationship with His Holiness the Dalai Lama through the Emory-Tibet Science Initiative. Recently the Tenzin Gyatso Science Scholars, who are Tibetan Buddhist monastics that reside and take courses on Emory's campus, were enrolled in a novel science research course designed and taught by undergraduate students at…

This study presents a conceptual framework for embedding interdisciplinary learning approaches in a postsecondary science program in order to foster interdisciplinary science habits in students. The framework was developed through the lens of a multi-year interdisciplinary postsecondary science program that encompasses a series of courses in which…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

Course-based undergraduate research experiences (CUREs) integrate authentic research into undergraduate chemistry laboratories, introducing students to research while simultaneously reinforcing fundamental concepts. Despite their ubiquitous nature in bioanalytical research, few CUREs have been published applying the fundamental techniques of…
